The wetness indicators of some of Merries’ nappies have turned partially green even before use. Why does this happen?

The wetness indicators are sensitive to moisture and wetness, and the colour changes from yellow to green. Hence, the indicators on a nappy may become greenish or partially green in colour due to the moisture in the air, even if the package is unopened.
Even though the indicators are partially green, it will turn dark green completely when your baby pees. The colour change does not affect the quality or performance of the nappy and is still safe for usage.
